Nuclear Safety 01
Nuclear Safety 01 : Nuclear safety covers the actions taken to prevent nuclear and radiation accidents or to limit their consequences. This covers nuclear power plants as well as all other nuclear facilities, the transportation of nuclear materials, and the use and storage of nuclear materials for medical, power, industry, and military uses. Although there is no way to guarantee that a reactor will always be designed, built and operated safely, the nuclear power industry has improved the safety and performance of reactors, and has proposed safer reactor designs. Mistakes do occur and the designers of reactors at Fukushima in Japan did not anticipate that a tsunami generated by an earthquake would disable the backup systems that were supposed to stabilize the reactor after the earthquake. According to UBS AG, the Fukushima I nuclear accidents have cast doubt on whether even an advanced economy like Japan can master nuclear safety. A map of Japanese nuclear power plants as they relate to the epicenter of the magnitude 9 earthquake and tsunami that hit the coast in March 2011, the closest reactor installation - Onagawa Nuclear Power Plant safely shut down as designed, however the older and further afield fukushima I power plant had its safety features overcome by the tsunami. In terms of proven safety, the Onagawa Nuclear Power Plant is a power plant design that has demonstrated it is possible for a properly designed nuclear power plant to safely accommodate one of the most powerful earthquakes and tsunamis ever recorded and to shut down safely as designed without incident
